cpu 1512sp 1-pn download error of Memory card not accepted

Dear all,

I had this strange error (Memory card not accepted or cannot be mounted ) with the CPU 1512sp 1-pn memory during the download of the plc program , i m using 4mb memory card for the program and the same card is using on the other CPU 1512sp 1-pn with out error. Did someone get this strange error? Thanks .

Please , you can see in attached the screenshot of error message .

Hi,

Could you please share with us the MLFB of the inserted Memory Card?

Is it by any chance a SIMATIC HMI Card?

I would also not rule out formatting this specific SMC, following the FAQ below:

How do you detect an inconsistently or incorrectly formatted SIMATIC Memory Card (SMC) and how do you repair it?

Hi , 

It's not the SIMATIC HMI Card? it 's the SIMATIC PLC Card and with this one we have downloaded plc program in the other cpu 1512 1-Pn .

thanks

Hi,

Hello AutoGen,

itafusna asked for the MLFB of your Memory card, that means the user wants to know the order number of your memory card.
Which one do you use?

Please have a look into the following FAQ:

What should you watch out for when loading the program of a CPU S7-1500 SIPLUS online to a SIMATIC memory card?

Hope it helps. 

Hi 

Thanks dear all, 

The MLFB of the inserted Memory Card is 6ES7954-8LC02-0AA0. (4 Mbyte)

This one can be used on an other cpu 1512  without problem.

Maybe the problem comes from the my old CPU 1512. Maybe the my old cpu 1512 is faulty? 

thanks again 

Hi,

as the same SMC works with another CPU without any issues, it is indeed possible that the SMC reader in the CPU is defective.

But you can check several things:

• Does the CPU accept another SMC or is this the same result?
• You can manually delete the project files (file "S7_JOB.SYS", folder "SIMATIC.S7S") from the SMC with a standard cardreader (no format!). Check if the SMC is accepted afterwards.
• Update the firmware of the CPU to the latest version available.

Hi Sancruz, 

Thanks for your answer, 

• Does the CPU accept another SMC or is this the same result?   Of course the same result with any SMC.

• You can manually delete the project files (file "S7_JOB.SYS", folder "SIMATIC.S7S") from the SMC with a standard cardreader (no format!). Check if the SMC is accepted afterwards.        The SMC had been  formatted with the another cpu 1200. But i have always the same issue

• Update the firmware of the CPU to the latest version available. Yes i did it , i have try to update to the last firmware but i have the same result.  
• 
  
• Maybe the SMC port is defected , do you know how to check this ? 

Hi,

I believe that the checks/results detailed in your last post are enough to determine that the SMC slot of this CPU is damaged.

Therefore, I would recommend you send the CPU to the Repair Service of your region.

Hi,

as it is the same result with any other SMC, too.... most likely the SMC reader in the cpu is defective.

There is not really a method to check this, besides the use of another SMC, which you already did.

You can send the CPU to the Siemens repair center to be checked.

***EDIT***

Sorry for posting the same thing, too. Post was already written in the meantime.

Thanks dear all, 

Of course this cpu must be check by Siemens. I will post back if the issue is result .

Best regard
